This invention relates to windows and more particularly to sash guides designed to permit the sashes of the window to be swung inwardly to facilitate cleaning thereof. l

In its broad aspects the invention contemplates the provision of swingable sash guidespivotally secured to the window casing and to each other in such a manner that the upper and lower sashes, as well as their guides, may be swung inwardly at the same time.

The invention also includes an arrangement oi' the pivotal connections between the guides such that in their normally closed position tle guides are substantially self -locked with respect to each other and to the casing.

A further improvement resides in the form oi sash weight suspension within theY casing and adjustable take-off rollers adapted to be swung into eilective position when it is desired to swing the sashes inwardly.

Other objects of the invention will be apparent from the following description thereof taken in connection with the accompanying drawings, in whichz- Fig. 1 is a side sectional elevation of the window illustrating the relative positions of the constituent elements when the window is fully closed;

Fig. 11 is a perspective of the swingable support for the take-off pulleys.

Referring to the drawings, the window comprises the usual casing 20 and sliding sashes 21, 22.A Interposed between the sashes and the casing, at each side thereof, `are metallic plates (Cl. 2li-45) 23 and hinged guide frames 24, 25, the latter being pivoted to swing about horizontal axes near the bottom and middle of the window respectively. Each of the upper guide frames is pivotally secured to plates 23 by means or" beveled 60 discs 26 welded to the frames and cooperating with undercut openings 27`in the plates. The lower guide frames are similarly pivoted to the plates by discs 28 cooperating with openings 29. y

It will be noted that the pivots are in line respectively with the vertical positions of the upper and lower sashes.

The guide frames areV each provided with a rear iiange 3l and channel members or guide strips 32 for guiding Athe sashes in'their normal. 70 Vertical sliding movement. The lower guide frame is somewhat wider than the upper frame, but when the frames are swung into Vertical alignment, flanges 31 and channels 32 are also in alignment to form a continuous guide groove for the sashes. The guide frames are cut away at 33 and 34 so that they may be swung into closed position without interference. Furthermore, the upper end of the lower guide is formed to be complemental with the cut-away portion of the upper frame, thus forming, when the frames are vertically aligned, practically a continuous frame from top to bottom.

The frames are connected at their top ends by connecting members 35, the connection being made by means of discs 36, 37, welded to the connecting members and fitting iniundercut openings 38 in the frames. The connecting member also is provided with a channel 32 forming one of the guides for the lower sash. It will be seen that the connecting member is forked at its upper end 39 for connection with a projection 4l on the upper guide frame. When the sashes are swung inwardly, their guides remainin substantially parallel relation since their pivot points remain xed and their upper ends are constrained to move together.

As will be seen from Fig. 1, pivot disc 36 is oiiset with respect to discs 26, 37, so that, as the sash guides are swung past the center line of fulcrum points 26, 37, the abutting ends of the guide frame tend to snap either inte fully closed position or partly open position. In this respect the frames are practically self-locking.

A semi-circular projection 40 on the upper 105 sash guide cooperates with a similarly shaped recess 40 in plate 23 properly to align the guides.

The upper end of guide frame 24 is spaced from the top of the window casing, this space n@ 65, parent that the frames cannot vbe swung' inward being lled by a swingable support 42 for takeoff pulleys 43, which are normally disposed in the counter-weight space of the casing. Short channel members 44 on this support form a continuation oi guide channels 32. Each pulley support is pivoted at 45 and normally lies flat against plate 23, being locked in its normal position by a pivoted latch member 46 having a ange 47 thereon designed to cooperate with notch 48 on a pin 49 secured to the plate. The support is swung out to position pulleys 43 in the path of weight ropes 51, as shown 'in Fig.

4, when the sash guides are to be lowered. Inv

order to free the support for swinging movement, latch 46 is turned until flange -4'7 disengages notch 48. After the pulleys have been positioned, the latch engages a second notch 52 to hold the support in this position. The support may, of course, be swung up to a horizontal position better to facilitate Stringing of the weight cords. A

The `method of counter-balancing the sash-es Vis illustrated in 2. A single rope er iieXi-.blc cable 51 on each side of the window is connected at each end-to one of the sashes. Counter-weights 53 are suspended from a bracket 54 carrying pulleys 55, 56. Pulleys 57, are mounted in bracket 59, while still another pulley 61 is Ysupported by a chain 62 hung from bracket 5S. The weight vrope passes around pulleys 56, 61, 55, 58, in the order named, the arrangement being such that the ,guide Vframes vmay be swung down to a substantially horizontal position due to the relatively long weight cord and the short travel of the weight :as compared with that of the sashes. Y

In Fig'. it will be noted that suitable weather stripping 63 is mounted on eachside .of the sashes, the stripping preferably being felt or other iiexible material fitting within brackets 64 and being pressed into channels .32 by bowed spring members 65. This insures weather-prooi` windows and prevents rattling of the sasnes in their gguides.

When the guide frames are in fully closed position, that is, in vertical alignment, Ythey are locked iiush against plate 23 by the latch Vdevice shown in Figs. 8, 9, and y10. 'The abutting ends '60, 60 of `the frames are inclined downwardly in the ldirection of closing so that vthe upper frame cannot be displaced without rst moving the llower` frames. The latch 66 is provided with a beveled semi-circular disc 67 'cooperatingwith an Vundercut semi-circular recess 68 in plate 23 when the latch is in the position indicated in Fig. 8, thus locking the lower frame to plate 23 and preventing any relative movement of the sash guides. When vit is desired to unlock the frames, the latch is rotated 180., the `semi-circular disc being removed from recess 68, whereupon the frames may be lswung on their fulcra.

ig. 3 illustrates the window in a partially open position for Ventilating purposes. It is apfurther while the upper sash -is in its `topmost position, nor ycan the lower frame be moved AVtoward closed position while latch 66 is in .the position shown, disc 67 being in abutting Yrelation to the edge of plate 23. It is also apparent that the lower sash cannot be raised -due to interference with the channel guide 32 on connecting member 35. While the window is thus opened for ventilation, it is locked against movement in leither directions'o that wind or manipulation from the exterior of the building cannot open or close the window further.

The casing is, of course, provided with a suitable opening 69 to permit access to the counter-weights. A closure plate '71 covers this opening, and when the sash guides are in their normal position, the opening and plate are covered.

From the foregoing description it :is obvious that the sashes may be raised and lowered in the ordinary way, but when it is desired to wash or repair the windows, the guide frames and lsashes may be swung inwardly simultaneously and made easily accessible. It is furthermore 'apparent that the guide frames may be spaced .a slight distance from each other for ventilating' purposes and eiectively locked in this position.

While a detailed description of a preferred embodiment of the invention has been incorporated herein, :it iis =to :be -understood that the invention .is not VLto be limited tothe .exact arrangement of the constituent elements illustrated, but that the invention .is :susceptible of :modification.
